    Abstract:
    The serum levels of soluble interleukin 2 receptor (SIL-2R) and tumor necrosis factor (TNF) were assessed in 69 children from 6 months to 14 years old who suffered from acute lymphoblastic leukemia (39), Hodgkin's disease (15), non-Hodgkin's lymphoma (15) and in 54 normal age-matched controls prior to any therapy and at remission. Both SIL-2R and TNF levels were significantly higher at diagnosis compared with normal controls (P < 0.001), but decreased significantly at remission. The SIL-2R and TNF levels were significantly higher in an advanced stage of lymphoma than in an early stage. In the patients with acute lymphoblastic leukemia (ALL) and lymphoma, higher levels of SIL-2R (> 1030 units/ml) and TNF (> 30 pg/ml) were associated with a poorer treatment outcome (P < 0.01). Our findings indicate that elevated TNF serum secretion together with SIL-2R are useful markers in childhood ALL and lymphoma and can be used to assess both disease activity and prognosis in this group of malignancies.
